By the time of ovulation, the male’s semen sample is treated in the laboratory, in order to obtain the best sperm. Afterwards, they shall be placed at the bottom of the uterine cavity, by means of a catheter.

In case of absence of sperm or genetic changes, anonymous donor sperm may be used (AID – Artificial Insemination with Donor Sperm).
